Multipath TCP (MPTCP)

Draft agenda [as at 15th March]

Friday 30th March
11.20am – 1.30pm (130mins)
Room 252B


Status – Chairs (10mins) [10:120]
Note well
Note takers, jabber scribe
WG Last Call completed successfully - thank-you!
TCP option kind request into IANA

WGLC changes - Brief update (10 mins) [20:110]
Protocol – Alan Ford
API - Alan Ford

Charter (40mins) [60:70]
We have completed our charter! So we should either re-charter or close.
The WG Chairs propose that we re-charter, as there is a lot of interest in MPTCP. Some potential topics:
* protocol bis for Standards track
* MPTCP proxy [possible starting point, draft-hampel-mptcp-proxies-anchors]
* document advice about implementation specific heuristics 
* hear about about experiments & experience and uses, applicability & maybe document them
* interop events
* are there any IETF issues that could help implementations, getting into Linux kernel etc?

Other topics that have been mentioned in the past
* MPTCP proxy for mobility (item above maybe covered above)
* Support for single-homed end systems [possible starting point, draft-wr-mptcp-single-homed]
* Alternative security
* Alternative congestion control
* Advanced api
